Abstract:Information Security has become important aspect now-a-days. For hiding secret information in images, there are various steganographic techniques. Some of them are more complex than others & all of them have strong & weak points. Algorithm for information hiding is design to obtain the three important parameters capacity, robustness & invisibility. This paper propose a novel reversible data hiding technique for digital color image. This technique guarantees effective retrieval of hidden data in color image without degradation in the quality of color image. The propose method makes use of Least Significant Bit (LSB) of three color channels that is red, green, and blue for embedding the secret data. The cryptographic methods are used to encrypt & decrypt the data to increase the security. The Genetic Algorithm (GA) is used for selection of optimized regions for hiding multiple data files.
